Question

Lights off three sides of a triangle are 1 is to 3 is to 5 and perimeter of the triangle is 270 find the sides​

Answer 1

Explanation:

Let the sides of triangles are 3x,4x and 5x.

And perimeter of the triangle is 144cm.

So , 3x+4x+5x=144

       12x=144

         x=12

so, the sides are triangle are 3(12)=36cm, 4(12)=48cm , 5(12)=60cm

so , the longest side is 60 cm.

Area of triangle =

s(s−a)(s−b)(s−c)

here , s=72 and a=36, b=48 c=60

                          =  

72(72−36)(72−48)(72−60)

                           =  

72(36)(24)(12)

                            =  (((((((if you get the time then u can be online at 1:30 to 2:00 in the noon))))))))

746496

                             = 864

So, the area of triangle is 864 cm

2

 and the height corresponding to longest side h=

60

2×864

=28.8cm
